  • a blinking light circuit in the handles provides interruptible power to the LEDs that are distributed in the transparent tube.
  • the handles contain batteries for supplying the power.
  • Such a jump rope produces light flashes as soon as the rope is rotating.
  • such a jump rope does not provide any information to the user about a parameter of the skipping action during the skipping action when the jump rope is rotating.
  • a first aspect of the invention provides a jump rope as claimed in claim 1.
  • a second aspect of the invention provides a system comprising the jump rope as claimed in claim 15.
  • a third aspect of the invention provides a system comprising a plurality of jump ropes as claimed in claim 16.
  • a fourth aspect of the invention provides a jump rope to be used in a system according to claim 16, as claimed in claim 17.
  • a fifth aspect of the invention provides a method of displaying information about a skipping action with a jump rope as claimed in claim 22.
  • Advantageous embodiments are defined in the dependent claims.
  • a jump rope in accordance with the first aspect of the invention comprises a first handle and a second handle for holding the jump rope.
  • a rope element which is rotationally connected between the first and the second handle, comprises light emitting devices that are distributed along at least a portion of the rope element.
  • the light emitting devices may be LEDs.
  • a display parameter unit determines a display parameter which provides information on the skipping activity when the rope element is rotating.
  • the display parameter is not an indicator that only indicates that the rope element is rotating; in contrast it is an indicator of a parameter of the skipping activity once the rope element is rotating.
  • Embodiments of the skipping parameter are claimed in claim 10.
  • the jump rope further comprises a driver circuit which drives the light emitting devices to change an appearance of the rope element in response to the display parameter. Consequently, the jump rope provides information to the user about a parameter of the skipping action during the skipping action. This information can be easily displayed to the user when the jump rope is in front of the user.
  • US2004/0218383 discloses a jump rope in which LEDs extend along the rope.
  • a stepper motor in the handle generates power for the LEDs.
  • the stepper motor has an axis which is connected to the rope. This axis starts rotating once the rope starts rotating with respect to the handle.
  • the rotating axis generates a voltage in the stepper motor which voltage is supplied to the LEDs.
  • the LEDs start producing light.
  • the light emitted by the LEDs only indicates whether the rope is rotating or not. This light does not give a discernable feedback to the user of a parameter of the skipping action once the rope element is rotating.
  • This prior art does not have the display parameter unit which uses the sensed parameter to provide information on the skipping activity when the rope element is rotating. There is no conversion from the voltage generated by the stepper motor to, for example, the rotational speed, or the number of revolutions.
  • the driver circuit separately activates the light emitting devices to obtain, in use, a two-dimensional image due to rotation of the rope element.
  • the movement of the line of LEDs is used to produce a two-dimensional image by the correct timing of on and off periods of the LEDs.
  • the skipping person or a spectator perceives a two-dimensional image because his or her brain remembers the sequentially displayed data by the moving one-dimensional array if the one-dimensional display moves sufficiently fast. This effect is also referred to as the after image effect.
  • the two-dimensional image may have many forms. The most interesting images indicate to the user a feedback on how good he or she is performing the skipping action. For example, a smiling smiley may be shown as long as the speed of rotation of the jump rope is higher than a particular desired speed, or is within a predetermined range of speed. The color of the smiley may indicate the deviation from the desired speed.
  • the two-dimensional image created when the jump rope is rotating comprises characters which indicate a value of the display parameter. For example, a number is displayed which indicates the speed of rotation, and/or the number of revolutions made so far.
  • a sensing unit senses the rotation of the rope element with respect to the first and the second handle to obtain a sensed parameter.
  • the sensing unit may comprise a mechanical, optical, magnetic, or capacitive sensor to sense when the rope passes along the sensor.
  • the rope element has to be locally adapted to allow the sensor to detect the rope when it passes the sensor.
  • a piece of magnetic material may have to be fitted to the rope element such that this piece of magnetic material passes along the sensor when the rope is rotating.
  • the display parameter unit generates the display parameter from the sensed parameter. For example, if the number of revolutions so far has to be displayed, the sensed parameter itself may be displayed. In another example, the time between the occurrences of two consecutive pulses of the sensed parameter is determined to calculate the speed of rotation of the jump rope if this speed has to be displayed.
  • the jump rope comprises a synchronization mechanism to synchronize the position of the image. If the LEDs have a limited on-time, which is especially true if the LEDs are used to present a two-dimensional image, this on-time is synchronized to at least present the information when the jump rope is in front of the user.
  • the synchronization may be obtained by determining a direction of rotation of the rope element (RE) and an instant at which the rope element (RE) passes a predetermined position with respect to the handles (Hl, H2). This is however not essential to the present invention because it is possible to provide several on-time periods such that the image is created several times. Always one of the images will be in a position in front of the user.
  • the synchronization is essential if a two-dimensional image has to be presented both in front of the user and at the back of user such that other people can also read the information, and if the information provided is orientation sensitive. Now, the image in front of the user should have the opposite top-bottom and left-right orientation of the image at the back of the user.
  • the synchronization mechanism comprises a rotation detector sensor fixed to the handle to detect the passing of the rope along the rotation detector.
  • the synchronization mechanism comprises a rotation detector which is rotationally mounted on the handle and which has a center of gravity at a predetermined distance from a rotation axis around which the rotation detector is rotational.
  • This rotation detector has now a fixed position independent on how the user holds the handle. In this fixed position, a line which connects the center of the rotation axis with the center of gravity is always pointing to the center of the earth.
  • the synchronization of the image position is performed automatically; it is not required to rotate the handles over a particular angle.
  • the synchronization mechanism may comprise both the rotation detector sensor of claim 6 which is fixed to the handle and the rotationally mounted rotation detector sensor of claim 7. Due to the skipping activity, the rotationally mounted rotation detector sensor may fluctuate around the correct average position. The average position may be used as an offset value to correct the actual position of the fixed rotation detector sensor. It is assumed that the actual position of the fixed rotation detector sensor is very stable once the skipping person holds the handles.
  • the rope element comprises different colored light emitting devices.
  • the driver circuit drives the different colored light emitting devices to obtain a combined light which has a color varying in response to the display parameter.
  • the color may indicate the deviation of the actual rotational speed of the jump rope from the desired speed, or the color may be an indication for the number of turns still to be made.
  • the different colors may be combined with flashing of different one of the colors or all the colors together. For example, a flashing red color which interrupts a white light indicates that the actual rotational speed is too low, but that the average rotational speed is still within the desired range.
  • the red light is obtained by decreasing the luminance (or switching off) the green and blue LEDs.
  • a continuously red color indicates that both the actual rotational speed and the average rotational speed is lower than a predetermined desired value.

  • the display parameter unit is at least one out of the group: actual rotation speed of the rope element, average rotation speed of the rope element over a predetermined period of time, number of revolution
  • the detection of the number of rotations and the generation of the time are well known in the prior art and are thus not further elucidated.
